You gotta keep temps up in the 60s at night; cold wet soil does not make a happy plant.

But seriously, look at you with your pots all lifted up on racks over the sexy leopard-print rug. Those racks are EXCELLENT. Just a FYI, anyone who uses grow bags benefits HUGE from something like that IMHO. Yay, freely-draining media!!! And they are beneficial to us pot growers too, lol.
